Just for general info....The link below shows the basic motor and shunt resistor set up for a Collaro Studio tape deck:

That broadly agrees with the motor circuit of the Elizabethan Major which also uses the Collaro Studio tape deck and also has a single shunt resistance.
The OP's tape recorder clearly has a dropper consisting of two resistances, as apparently the Martin Recordakit did:

The two resistors have been mentioned before:
